CHARLES C. MCINTOSH, DECEASED, LATE 0F PORTLAND, OREGON, BY MARGARETMOINTOSH, ADMINISTRATRIX, OE "PORTLAND, OREGON.

C'QNVEYER. MEANS FOR EXHAUST OR COOK BOXES.

To all whom it may concern Be it known that CHARLES C. McINrosH,deceased, late a citizen of the United States, and resident of the cityof Portland, Multnomah county, State of Oregon, did invent a certain newand useful Improvement 111 Conveyer Means for Exhaust or Cook Boxes, ofwhich the following is a speclfication.

This invention relates in a general way to the so-called exhaust box orcooker used 1n canneries, through which the cans are run for a definiteperiod, and has partlcularly to do with the means for conveying the cansthrough the exhaust box One of the objects of this lnvention is toprovide simple and positive can-conveyingmeans operating in a horizontalplane.

To this end the improvement comprises a plurality of trackways arrangedside by side, cooperative advancing means for each trackway, and otheradvancmg means connecting the ends of the ad acent trackways forcarrying the can'from one trackway to the other, and thus through theexhaust box. A short-cut conveying means is provlded whereby the timerequired for carrying the cans .through the box is shortened withoutFig. 1 is another fragmental view showing a detail of constructionconcerning a removable rail located at the inlet end of the exhaust box.this rail being shown in broken lines of Fig. 1; Fig. 2 is a verticalsection taken on the line 22 of Fig. 1; Fig. 3 is a larger sized detailof a preferred type ofan endless screw used as the conveyor, and

illustrates the mode in whichthe cans are advanced along a trackway;Fig. 4 is a sectional end elevation of the parts shown in Fig. 3,showing in addition the rails of the trackway over which the cans aremoved by the conveyor means; Fig. 5 is-a fragmental front elevation ofthe machine, showing the Specification of Letters Patent.

indicator element and the handle of the means provided for moving therails of the trackways closer together and farther apart so as toreceive cans of difierent sizes; Fig. 6 is a diagrammatic view showingthe means employed by me for so supporting the rails of the trackways asto rende them laterally movable; and Fig. 7 is a larger-sized sectionalView showing a portion of the screw conveyer running lengthwise of thetrackway, one of the transverse screw conveyers connecting the ends ofadjacent trackways, and the adjustable guide cooperating with saidtransverse screw conveyer.

' The device comprises a box or housing, a, mounted on the supportingbase legs I). A number of transverse frame members, d, having legs a?and cross beams 03 are mounted on the floor, 0, of the box. The crossbeams d support the can conveyer mechanism, while underneath and on thesides are the steam pipes e.

The can-conveying means consist of a plurality of trackways, f, arrangedside by side, each having two rails f, f. The can is advanced along thetrackway by a screw conveyer g, the thread g of which is preferably madesquare-face so as to be adapted for engaging the crimped edge at thebottom of the cans h, as illustrated in Figs. 3 and 4.

'The screw conveyors are driven through a motion-transmitting element2', and the connecting pinion elements j, k.

In order to adapt the trackways f to receive cans of different sizes,the rails of the trackway are so arranged as to be laterally movable.For this purpose I prefer the ar-' rangement more clearly illustrated inFigs.

1, 2 and 6. Z, m are two transversely sliding bars supported in bearingsn mounted on the cross beams d Each sliding bar carries the chairs Z, m,of one rail of the trackway. On the bottom of these chairs Z, m aresecured angle rails f. and at the top of said chairs are fastened siderails 72".

Each slide bar is provided on its lower edge with a rack portion, asindicated at 12 and m in Fig. 6. Supported on the lower side of thecross beams d of the frame member d are bearings (Z for the two paralleladjusting shafts p, g. Said shafts have pinned on them the pinions p, g,which mesh with said rack portions 12, m On the extreme end of theshafts p, q are the pinions 11 9 (see Figs. 1 and 5) which mesh witheach other. Fixed on the end of the shaft 10, outside of the cook box,1s an adjusting lever 72 the transverse conveyer (1") will lie in thesame plane it is necessary to make the transverse screw conveyers ofgreater dlameter. The transverse screw conveyers are con stantly drivenby the motion conveying element 11 by the gears r r See Fig. 1. Boltedon the cross beams of the endframe members are the fixed Zplates 8. Seedetail Fig. 7. Parallel to the shafts r and on a shaft t are journaledthe arms t for adjusting the. transverse guides. The latter carries anumber of guide rails t, F, t which are located in varying levels; andthe surfaces of these guide rails are so inclined that by the rotationof the arm t about the shaft t they may be arranged to lie in horizontalplane. The means for adjusting the arm 25 are shown in Fig. 1*. Aneccentric stop-lug u is rotatably mounted on a pin u inside of the steambox, and the lever t fixed on the shaft 25*," is supported in place bythis stop. As the arm 23 has three positions, the stop lug u is madewith three differentlylocated flat faces, each arranged to so hold thelever arm t as to' bring either of the three surfaces i t of the guiderails into active position. These guide rails are provided only at thatside of the screw conveyers 1" toward which they turn, since the canwould have a tendency to run off on such side only.

As designed, the time elapsing between the inlet and outlet of the cansfrom the box would be about five minutes; but there is also providedmeans by which this time may be cut down without making any change inthe speed of the machine. Said means consist of a short out, by whichthe travel of the can along'tw adjace'nt trackways is el mlnated. Forthispurpose a removable rail section f is provided in one rail 7 (seeFigsl 1 This removable rail section has A set screw f, sliding on a bar7, holds the removable 'rail on its ower end an ear f section in place.When it is desired that the cans traverse all of the trackways, thisremovable rail section f lis placed in the posit on shown in Fig. 1 andshown in broken outline in Fig. 1; and when it is desired to eliminatethe travel of the cans over the first two trackways, the rail section fis removed. In this way when the can has reached the first transversescrew conveyer indicated by A in Fig. 1, the can will be shunteddirectly over to the middle trackway, and then be carried up and downthe trackways.

What is claimed:

1. In a device of thecharacter described,

in combination with conveying means, a

trackway comprising parallel slide-bars movable transversely to thelength of the trackway, chairs for one rail of the trackwaycarried byeach slide bar, angle rails fastened on the bottom of the chairs andside rails fastened to the top of the chairs, and means for moving theslide bars simultaneously in opposite directions.

2. In a device of the character described, in combination with conveyingmeans, a trackway comprising parallel slide bars movable transversely tothe length of the trackway, chairs for one rail of the trackway carriedby each slide bar, angle rails fastened on the bottom of the chairs andside railsfastened .to the top of the chairs, rack-portions at thebottom of each slide bar, pinions meshing with said rack portions, andmeans for simultaneously rotating the pinions.

3. In a device of the character described, the combination of aplurality of parallel conveyers, guide rails at the sides of andseparating such conveyers, the guide rail separating adjacent conveyersbeing made with a removable section located intermediate its ends, andan auxiliary transverse conveyer located at such removable section,whereby, when the latter is removed, the article carried between theguide rails of one conveyer is shunted to the adjacent conveyer.

4.

5. In a device of the character described, the' combination with canadvancing means, of a supporting element cooperating with the advancingmeans and comprising a fulcrumed arm, a plurality of guide rails carriedby the arm, such guide rails located in varying levels, and means forsecuring said arm in place. v

6. In a device of the character described, the combination withcanadvancingmeans, of a supporting element cooperating with the advancingmeans and comprising a fulcrumed on an axis parallel to that of theendless screw, a plurality of guide rails carried by the arm, such guiderails located 15 in varying levels, and means for securing said arm inplace.
